The rectangle below has an area of x ^ 2 - 9 square meters and a width of x - 3meters

16.80 times .20= 3.36

step-by-step explanation:

- (2, -7)

- lines r and s and lines t and u must be parallel

answer: i think you should do the math and pay attention in class : )

step-by-step explanation:

that is truly what   think but if i get the answer i will

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
